Hi!
I just noticed these entries in my event log after moving a server from one datacenter to another:
16s eth0 IPv6 removed: 2001:9e0:803::30/64 16s eth0 IPv6 removed: 2001:9e0:803::30/64 16s eth0 IPv6 added: 2001:9e0:803::30/64 16s eth0 IPv6 added: 2001:9e0:803::29/64 16s eth0 IPv4 removed: 94.142.242.217/28 16s eth0 IPv4 removed: 94.142.242.210/28 16s eth0 IPv4 added: 83.247.10.30/27 16s eth0 IPv4 added: 83.247.10.29/27
As you can see the IPv4 added and removed lines make sense: remove two addresses from 94.142.242.x/28 and add two addresses in 83.247.10.x/27. The IPv6 addresses are wrong though: It *should* have logged two removals from 2a02:898:148::x/64 and two adds in 2001:9e0:803::x/64, but it logs one of the newly added addresses as removed twice.
Here is a diff to fix the bug:
